I don’t have information on this cultivar, so this article describes Aesculus × carnea, a natural hybrid between red buckeye (Aesculus pavia)
and horse chestnut
(Aesculus hippocastanum). Mature red horsechesnut reaches heights of 40-70' (12-21 m). It tends to be symmetrical in shape, looking a bit like a rounded cone.

Identification: Red horsechesnut is not native to the United States,
but it is found throughout zones 5-7.[1] The beautiful pink blossoms make it a popular planting in yards
and along streets. The tree has wide green leaves composed of five leaflets. Nuts are round,
with thorny coats.

Edibility: Poisonous. The nuts of this and other horse chestnut
trees contain a dangerous glycoside.
